c# - 使用关键字this.实现构造函数有什么区别？

Question

请你解释一下这两个构造函数的实现有什么区别:

 public User(string a, string b)

    {

        name = a;

        location = b;

    }

还有这个:

  public User(string a, string b)

    {

        this.name = a;

        this.location = b;

    }

从编译器的角度来看，我没有看到任何区别。请解释一下。

Answer 1

没有区别，

this 只是引用类，如果您传入的参数与类中的字段具有相同的名称(以区分它们)，那么它很有用

public class Employee
{
    private string alias;
    private string name;

    public Employee(string name, string alias)
    {
        // Use this to qualify the members of the class 
        // instead of the constructor parameters.
        this.name = name;
        this.alias = alias;
    }
}
